This is ultimate melee
You have to attack him from all sides (partners) when he bends down attac him with EVERYBODY!!!!!!!!!!!!!!!!!!!!!!!
Keep doing this
When you get him downto 1/3 health he will power up.
Block his attacs (he will only attack the person you are controling)
Mean While Haveyour partners attack him TOGETHER!!!!
He will crouch down
You know the drill
